This invention` relates to improvements in cocks for.

hotties, jugs, and, other like articles, and consists of a cock attached to the cork .01j other plug, and having a turning plug, provided with a loose key for operating it,'the said cock4 having at the end of the tube projecting through the cork a' pair of wing or frictionplates, so connected to it andl hearing against the inner walls of the bottle thatya slidingv tube or apiece of steel or other wire within the cock-tube, and acted on b v the cock-plug .when turned to stop the passage of the liquid, will force the wing-plates against the walls ofthe bottle, so as to prevent the withdrawal of the cork. l v f Figure 1 is a sectional elevation of my improved bottle-cock, and I o v a Figure 2 is another sectional eleration,taken`at right angles to the section g. '1. f

A is the cock-tube, It extends through the .cork B and receiveslthrough opposite openings in thesides, below the cork, the end C of the curved wing or friction-plates D, whichhear against the inner walls of the neck of the bottle.v

E is an inner tube, or it may be a rod` of wire placed e of the friction-plates..v ,Y i .g Y This tube is beveled at the upper end, so that ythe f r vwithin the tube A, between the plug and the endsvvtl,

y'plug F, turning in the direction indicated by the ar-` s jm' row, will force the tube down on the ends Cy of the l plates D, and force-the latter against `the side of the bottle, to hold thecork B against being drawn out a.t 1 the same time that the passagefor the contents cfg. l

the bottle is closed .by the plug F.

Th latter is shaped at the place furthe passagcof l the liquid in theellipticvform shown in cross-section *in fig' 250 that when turned againstbe beveled llpv y per end of the wire inthe direction represented-by the arrow, itfwill not be'obst-ructedtherehy. f .n When the plug Finis turned to allow the. liquid t-o escape, the weight ofthe "plates D willraise 'the tube,v 'y i y A, and the'plates will be tree vto allow the withdrawal otfffk f y I the cork if desired.

The tubeA is madein twopai'ts, screwing'ptogether at the top of the cork, softhat the part with the' plug` may be readilyrattached ordetached, as required for ilse. 1 'f y Having thus described my invention,
